Patent JP-H0380235-A (JP)
Title: Camera
Inventor: MURAMATSU MASARU
IPC: G03B9/08
Filed: 1989-08-23
Abstract: PURPOSE:To photograph a picture in focus by processing two or more previous defocuses, accurately finding a time at which release is started, and releasing a shutter at the timing which is earlier by the period of time corresponding to a release time lag. CONSTITUTION:The camera is provided with a focal point detecting device 4, a storage device 5, a time measuring device 6, a device 7 which predicts a time at which defocus becomes minimum, an interrupt timer 8, and a release processor 9. A time at which defocus becomes minimum is found by plural defocuses, which are obtained by the focal point detecting device 4 which detects defocus of an object, and the times at which the defocuses were detected. By starting the release earlier by the period of time corresponding to the release time lag so that the shutter is released at that time, the shutter is released at the timing of the minimum defocusing even when the object moves speedily or a speed at which the lens is drawn is high. Thus, a picture in focus can be securely photographed even if there is a release time lag.
Patent JP-H0380324-A (JP)
Title: Central processing unit
Inventor: YAMAURA SHINICHI
IPC: G06F9/302
Filed: 1989-08-23
Abstract: PURPOSE:To shorten the arithmetic processing time by inhibiting a carry or take-down operation to the higher rank data if no carry and take-down operation is carried out according to the arithmetic result of the lower rank data and therefore omitting the storage of the arithmetic result into a memory. CONSTITUTION:A central processing unit (CPU) consists of a control part 1 which controls the execution of an instruction containing an operation code IR 6, a pre-byte IR 7, etc., and an arithmetic part 2 including an ALU 3, a data bus 4, etc. The ALU 3 decides whether the produced carry is equal to 1 or not. Then the ALU 3 does not carry out an operation to add 0 to the higher rank data and fetches the next operation code since no change is produced to the higher rank data if the carry is equal to 0. Thus it is possible to omit a conventional cycle where 0 is added to the higher rank data and this addition result is written in a memory. Thus the addition of the carry is stopped to the higher rank data and the writing operation is omitted to the memory when no carry is produced. As a result, the arithmetic executing time of the CPU is shortened.

Title: Auto-focusing device
Inventor: OTAKE YOSHITOMO
IPC: G02B7/38
Filed: 1986-09-17
Abstract: PURPOSE:To just focus a device on plural objects, which are different in distance from the element surface of an image pickup element, simultaneously by oscillating a lens or the image pickup element at a high speed by an oscillating means. CONSTITUTION:A focusing lens 2 as the lens which forms the image of the image pickup light from an object on an element surface 1a of an image pickup element 1 is oscillated at a high speed with about 60Hz in the direction of the optical axis by an oscillating means 3 using a piezoelement. Since the image of the image pickup light from plural objects different in distance from the element surface 1a is repeatedly formed at the period of high-speed oscillation, the result that respective objects are just focused simultaneously is attained by the after-image effect of human eyes.

Abstract: PURPOSE:To enable a T-type opening to be formed even without using an electron beam exposure device and mass production property to be increased by constituting a coated layer with a plurality of layers and increasing etching rate of layers out of a plurality of layers as they are further away from a semi-insulation substrate. CONSTITUTION:A dummy gate 2 is formed on a semi-insulation substrate, for example a GaAs wafer 1.

IPC: H02M7/48
Filed: 1985-09-30
Abstract: PURPOSE:To improve efficiency by removing effects on the charge and discharge of a capacitor and an output waveform by inserting a dummy resistor. CONSTITUTION:A main circuit for an inverter device consists of open/close switching elements S1-S4, etc., converts DC into AC, and feeds electricity to load L through a filter F and a transformer T. Said switching elements S1S4 are driven by control pulses from a control circuit CONT.

Consequently, the semiconductor switch element S5 is conducted by control pulses for period extending over positive and negative periods approximating to the zero voltage of AC output voltage while using zero voltage as a reference (the center), and the dummy resistor R' is closed during that time. Accordingly, the charging charges of a capacitor CX are discharged, thus improving the waveform of output voltage.

Abstract: PURPOSE:To obtain a liquid crystal panel type light modulator of small light loss with simple constitution by penetrating an optical fiber through the liquid crystal and exposing the core. CONSTITUTION:An optical fiber 10 is penetrated through a liquid crystal cell provided with a substrate 11, a sealing material 14 and transparent electrode films 12, 13, and the clad part 10b of the optical fiber 10 which is in contact with the liquid crystal 15 is stripped off to expose a core 10a. When a voltage is not applied to the electrode film 12, 13, the longer axes of liquid crystal molecules are arranged in the direction of optic axial of the optical fiber, and when the voltage is applied in the direction perpendicular to the optic axis. The refractive index of the liquid crystal becomes an extraordinary light refractive index etae and an ordinary light refractive index etao, respectively. The refraction index etac of the optical fiber core becomes etae>etac>etao. As the liquid crystal acts as a clad, light is transmitted in the core 10a when a voltage is applied, and not transmitted in the core 10a when a voltage is not applied. By this way, a liquid crystal panel type light modulator of small light loss can be obtained with simple constitution.

Abstract: PROBLEM TO BE SOLVED: To improve the operating efficiency of a voice memory medium by eliminating automatically a busy tone included in the recorded voice when the user during recording operation hooks on to terminate the recording before the elapse of a message recording enable time. SOLUTION: When a BT detection section 4 detects a BT from a PSTN 7 on a voice signal bus 8, it is reported to a central processing unit 6 via a control bus 9. The central processing unit 6 discriminates how much degree of length of BT is included and calculates the time and the data byte number. Then the central processing unit 6 commands the revision of an end point of voice data stored in a voice memory 3 based on the calculated information to a recording reproduction processing section 2.  That is, the central processing unit 6 shifts a recording end point of voice data stored in the voice memory 3 ahead from a point of time T3 to a point of time T2 obtained by subtracting a time of (BT period count × BT detection number) from the point of time T3 and uses a time from a recording start point of time T1 to the recording end point of time T2 as a valid voice data part V for the recording.
